Коль скоро манометр работает неправильно, диспетчерская вызовет мастера проверить теплообменник.

Here коль скоро means since, given that, or if it turns out that.

It is understandable, but it sounds bookish, formal, or a bit old-fashioned in modern Russian. In everyday speech, a learner is much more likely to hear:

• если = if
• раз = since / if
• поскольку = since / because

So this sentence could be rephrased more neutrally as:

• Если манометр работает неправильно, ...
• Поскольку манометр работает неправильно, ...

Also, коль скоро here does not mean as soon as in the simple time sense. For as soon as, Russian normally uses как только.

Because Коль скоро манометр работает неправильно is a subordinate clause, and it is followed by the main clause:

• subordinate clause: Коль скоро манометр работает неправильно
• main clause: диспетчерская вызовет мастера проверить теплообменник

Russian normally separates this kind of clause with a comma, just as English often does with Since... , ... or If... , ....

Because манометр is the subject of работает.

In this clause:

• манометр = the pressure gauge
• работает = works / is functioning

The subject is in the nominative case, so you get манометр.

Because неправильно is an adverb, and it modifies the verb работает.

The sentence is saying that the gauge works incorrectly / functions improperly, not that the gauge itself is incorrect as a noun phrase.

Compare:

• неправильный манометр = an incorrect / faulty gauge as a thing
• манометр работает неправильно = the gauge is functioning incorrectly

So the adverb is the natural choice here.

Yes. Literally, диспетчерская is a dispatch room, control room, or dispatcher’s office.

In technical and administrative Russian, it is very common for a place or department name to stand for the people working there. So here диспетчерская вызовет мастера means:

• the dispatch office will call a technician
• more naturally in English: the dispatcher/control room will send for a technician

So grammatically it is a noun meaning a place/department, but semantically it refers to the people acting from that office.

Вызовет is the simple future of the perfective verb вызвать.

That tells you two things:

1. The action is in the future: it will happen.
2. It is viewed as a single completed action: the dispatch office will place the call / summon someone.

This is very typical in Russian:

• imperfective вызывать = to call/summon in general, repeatedly, or as a process
• perfective вызвать = to call/summon once, successfully, as a complete event

Since the sentence refers to one specific future response, вызовет is the natural choice.

Because мастера is the accusative singular of an animate masculine noun.

The noun is мастер. After вызовет, it is the direct object: the dispatch office will call the technician.

For masculine animate nouns in Russian:

• nominative singular: мастер
• accusative singular: мастера

So this is a classic animate accusative pattern.

In this context, мастер usually means a technician, repair specialist, maintenance worker, or service engineer.

It does not necessarily mean master in the English sense of someone highly accomplished at an art or craft.

In technical or workplace Russian, вызвать мастера is a very normal phrase meaning to call in a technician.

Because Russian often uses a direct infinitive construction after verbs like send, call, invite, ask, or force, when the person mentioned is the one who will perform the infinitive action.

So:

• вызовет мастера проверить теплообменник

means:

• will call a technician to check the heat exchanger

The infinitive проверить is understood as the technician’s action.

If you used чтобы, the structure would usually need to be expanded, for example:

• диспетчерская вызовет мастера, чтобы тот проверил теплообменник

That is also correct, but it is a bit heavier and more explicit. The original sentence is more compact.

Because проверить is perfective, and here the sentence refers to one complete checking action.

The idea is not that the technician will be engaged in checking as an ongoing process in general, but that he will carry out a check.

Compare:

• проверить = to check, to inspect, to verify once and completely
• проверять = to be checking, to check repeatedly, or in a more process-oriented sense

In this sentence, проверить is the normal choice.

Теплообменник is in the accusative case, because it is the direct object of проверить.

The technician will check what?
теплообменник

Since теплообменник is a masculine inanimate noun, its accusative singular looks the same as the nominative singular:

• nominative: теплообменник
• accusative: теплообменник

So the form does not change here.

The word order is fairly flexible, but the original order is natural because it puts the condition first.

Original:

• Коль скоро манометр работает неправильно, диспетчерская вызовет мастера проверить теплообменник.

Possible rearrangement:

• Диспетчерская вызовет мастера проверить теплообменник, коль скоро манометр работает неправильно.

That is grammatical, but it sounds more marked or literary. In ordinary speech, many speakers would simply replace коль скоро with если or поскольку.

Russian word order often changes to adjust emphasis, style, or information flow, not basic grammatical relations.

It sounds technical and somewhat formal, mainly because of:

• коль скоро — bookish/formal
• диспетчерская — institutional/technical wording
• теплообменник — specialized technical vocabulary

A more neutral everyday-style version might be:

• Если манометр работает неправильно, диспетчерская вызовет мастера проверить теплообменник.

Or even more conversationally, depending on context:

• Если манометр неисправен, диспетчерская вызовет мастера проверить теплообменник.

So the original sentence is fully understandable, but it belongs more to a formal or technical register than to casual conversation.
